Changed Classes and Interfaces
AccessControlContext An AccessControlContext is used to make system resource access decisions based on the context it encapsulates.
AccessControlException

This exception is thrown by the AccessController to indicate that a requested access (to a critical system resource such as the file system or the network) is denied.

AccessController

The AccessController class is used for access control operations and decisions.

AlgorithmParameterGenerator The AlgorithmParameterGenerator class is used to generate a set of parameters to be used with a certain algorithm.
AlgorithmParameterGeneratorSpi This class defines the Service Provider Interface (SPI) for the AlgorithmParameterGenerator class which is used to generate a set of parameters to be used with a certain algorithm.
AlgorithmParameters This class is used as an opaque representation of cryptographic parameters.
AlgorithmParametersSpi This class defines the Service Provider Interface (SPI) for the AlgorithmParameters class which is used to manage algorithm parameters.
AllPermission The AllPermission is a permission that implies all other permissions.
BasicPermission The BasicPermission class extends the Permission class and can be used as the base class for permissions that want to follow the same naming convention as BasicPermission.
Certificate

This is an interface of abstract methods for managing a variety of identity certificates.

CodeSource

This class extends the concept of a codebase to encapsulate not only the location (URL) but also the certificate(s) that were used to verify signed code originating from that location.

DigestException This is the generic Message Digest exception.
DigestInputStream A transparent stream that updates the associated message digest using the bits going through the stream.
DigestOutputStream A transparent stream that updates the associated message digest using the bits going through the stream.
DomainCombiner A DomainCombiner provides a means to dynamically update the ProtectionDomains associated with the current AccessControlContext.
GeneralSecurityException This is the general security exception class which serves to group all the exception classes of the java.security package that extend from it.
Guard

This interface represents a guard which is an object that is used to protect access to another object.

GuardedObject A GuardedObject is an object that is used to protect access to another object.
Identity

This class represents identities: real-world objects such as people companies or organizations whose identities can be authenticated using their public keys.

IdentityScope

This class represents a scope for identities.

InvalidAlgorithmParameterException This is the exception for invalid or inappropriate algorithm parameters.
InvalidKeyException This is the exception for invalid Keys (invalid encoding wrong length uninitialized etc).
InvalidParameterException This exception designed for use by the JCA/JCE engine classes is thrown when an invalid parameter is passed to a method.
Key The Key interface is the top-level interface for all keys.
KeyException This is the basic key exception.
KeyFactory Key factories are used to convert keys (opaque cryptographic keys of type Key) into key specifications (transparent representations of the underlying key material) and vice versa.
KeyFactorySpi This class defines the Service Provider Interface (SPI) for the KeyFactory class.
KeyManagementException This is the general key management exception for all operations dealing with key management.
KeyPair This class is a simple holder for a key pair (a public key and a private key).
KeyPairGenerator The KeyPairGenerator class is used to generate pairs of public and private keys.
KeyPairGeneratorSpi

This class defines the Service Provider Interface (SPI) for the KeyPairGenerator class which is used to generate pairs of public and private keys.

KeyStore This class represents an in-memory collection of keys and certificates.
KeyStoreException This is the generic KeyStore exception.
KeyStoreSpi This class defines the Service Provider Interface (SPI) for the KeyStore class.
MessageDigest This MessageDigest class provides applications the functionality of a message digest algorithm such as MD5 or SHA.
MessageDigestSpi This class defines the Service Provider Interface (SPI) for the MessageDigest class which provides the functionality of a message digest algorithm such as MD5 or SHA.
NoSuchAlgorithmException This exception is thrown when a particular cryptographic algorithm is requested but is not available in the environment.
NoSuchProviderException This exception is thrown when a particular security provider is requested but is not available in the environment.
Permission Abstract class for representing access to a system resource.
PermissionCollection Abstract class representing a collection of Permission objects.
Permissions This class represents a heterogeneous collection of Permissions.
Policy This is an abstract class for representing the system security policy for a Java application environment (specifying which permissions are available for code from various sources).
Principal This interface represents the abstract notion of a principal which can be used to represent any entity such as an individual a corporation and a login id.
PrivateKey

A private key.

PrivilegedActionException This exception is thrown by doPrivileged(PrivilegedExceptionAction) and doPrivileged(PrivilegedExceptionAction AccessControlContext context) to indicate that the action being performed threw a checked exception.
ProtectionDomain

This ProtectionDomain class encapsulates the characteristics of a domain which encloses a set of classes whose instances are granted a set of permissions when being executed on behalf of a given set of Principals.

Provider This class represents a "provider" for the Java Security API where a provider implements some or all parts of Java Security.
ProviderException A runtime exception for Provider exceptions (such as misconfiguration errors) which may be subclassed by Providers to throw specialized provider-specific runtime errors.
PublicKey

A public key.

SecureClassLoader This class extends ClassLoader with additional support for defining classes with an associated code source and permissions which are retrieved by the system policy by default.
SecureRandom

This class provides a cryptographically strong pseudo-random number generator (PRNG).

SecureRandomSpi This class defines the Service Provider Interface (SPI) for the SecureRandom class.
Security

This class centralizes all security properties and common security methods.

SecurityPermission This class is for security permissions.
Signature This Signature class is used to provide applications the functionality of a digital signature algorithm.
SignatureException This is the generic Signature exception.
SignatureSpi This class defines the Service Provider Interface (SPI) for the Signature class which is used to provide the functionality of a digital signature algorithm.
SignedObject

SignedObject is a class for the purpose of creating authentic runtime objects whose integrity cannot be compromised without being detected.

Signer This class is used to represent an Identity that can also digitally sign data.
UnrecoverableKeyException This exception is thrown if a key in the keystore cannot be recovered.
UnresolvedPermission The UnresolvedPermission class is used to hold Permissions that were "unresolved" when the Policy was initialized.
